[Q] [L7][P700][Bricked] Hard bricked Optimus L7 P700 - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hey guys,
Yesterday I tried unlocking my phone using the tools provided on this forum, but somehow my device got hard bricked.
It is just laying there with a black screen. It won't turn on, won't boot into recovery or emergency mode. Nothing.
But when I connected it to my PC (running Windows 7), I did hear the sound that it recognised it as a device, it just couldn't find any drivers for it, so I wen't to look into that.
Landed on the debricking method using QPTS on the CyanogenMod forums and I managed to find drivers for Windows 7, so no need for an XP computer!
There were some other Optimus L-series brickers who gave up on the process, but I have still some hope left.
Did all the work that had to be done, decompiled V20D KDZ for our device, converted the first 512 bytes of the partition.bin to .mbn, installed QPTS, and so forth.
Hooked up my phone to the pc holding the volume-down button, and QPTS actually recognised it as a phone in downloading mode!
Then that's where I got stuck. Using the HEX files from this thread, I get the following error:
Code:
Status: Software Download Aborted
Errors: Could not determine the HEX file's scrambling method. The file is invalid.
Do any of you have a clue on how get things working again?
The QPTS tool only lists MSM7x30 (eMMC) as ARMPRG to use for the phone in dowload mode, not the MSM7x27a we are using. Might this be part of the problem?
Any help is highly appreciated!

Can you go to emergency or download mode?
Battery taken out, hold the vol up + connect to usb, connected to the pc. Then you will see in a green screen with emergency mode.
Once your done that, be sure you installed the LG drivers, flashed through kdz.
You can use homero's v20 stock, it's already had cwm and unlock bootloader and v20 baseband.

Nope, can't get into emergency mode, screen stays black, no matter what. So yeah, just flashing a new KDZ isn't an option. :crying:

Does the kdz flasher recognized the phone? If it's turn on and connected to the PC.

You should try launching emergency mode some more. Install lg drivers. Take out battery, hold Vol up button and plug in usb. Make sure port works.

Thanks for the replies, guys!

I can't turn the device on. When I connect it to the PC, Windows sees the phone as an 'Unknown Device', even with the latest LG drivers installed.
And by KDZ flasher you mean the BC2App, right?

Tried it a dozen times, with different combinations too. Only thing that happens is the sound windows makes when a device is plugged in.

Any chance a method like this would work? If the .img.zx file would be edited for our device ofcourse.

Hey all,
I couldn't get any further debricking my phone myself, so I just brought it to a repair shop. I'm hoping they can do something using JTAG or something.
Regardless of getting my phone working again (hopefully), I would still love to see if we can find a way to debrick hard bricked devices. If we can find a solution, I'll volunteer for writing a tutorial

My P705 in emergency mode and Not being detected by the computer

I installed 10k rooted on my P705 and was about to install a custom recovery, when the phone came on it was in emergency mode but the computer could no longer detect it, I have tried all the usb ports on about 4 computers and changed the cable trice, So I'm a little bit sure it's nothing to do with the pc. I have tried putting it on holding volume + and -. Any help will be really appreciated because I am stuck right now.
I have gone through the forum for like 6 hours, I couldn't find anything , I apologize before hand if this was treated elsewhere.
Did you try flashing your stock firmware with Software update [KDZ] 1.0.4.4 (KDZ-Flasher) while in emergency mode?
Remove the Drivers and plug the phone in our PC.. maybe reinstall the Drivers
yes I did try to flash it but the computer doesn't detect it in the first place. So I get a " no phone found"

thank you but that didn't work either
Just to be clear, you're trying to flash your stock firmware with Software update [KDZ] (KDZ-Flasher), while in emergency mode (your phone in is that yellow emergency mode)?
If so, then maybe try the LG MOBILE SUPPORT TOOL.
I'm not familiar with it, but I read here that it's an alternative to Software update.

Thanks but Thats not exactly the problem, It DOES NOT READ to begin with. If the laptop could detect the phone, then I would be able to flash "anything". My problem is the laptop cannot detect the phone....
I'm confused - what do you mean by "DOES NOT READ"?
Your wrote that you are getting "no phone found" in Software update [KDZ].
So I asked if this is happening when you are in the emergency mode (your phone screen is kind of yellow and there is "emergency mode" in it).
I also wrote that if you were in emergency mode, then try LG MOBILE SUPPORT TOOL.
use another computer, maybe a problem with your OS (windows)

Heres the problem, its not detecting, If you can tell me some way to make the laptop detect the phone in emergency mode, I will be extremely grateful, ps kdz equally says no phone found cuz.... the laptop cannot detect the phone and LG MOBILE SUPPORT TOOL equally cannot find the phone connected to the laptop.

Okay, I got it.
Did you install the latest drivers?
If not, you can do so by downloading and installing them from your support site or by downloading and installing LG PC SUITE.
After that please open device manager and see if there's anything there with an exclamation or a question mark. If there is, please don't continue and post back what it is.
Only when you see that everything is okay, disconnect your phone, turn it off, enter into emergency mode (by clicking volume up + volume down + power button), make sure that you're in emergency mode (the yellow screen), connect your phone, run Software update [KDZ] (KDZ-Flasher), make sure to set the right type (CDMA / 3GQCT), make sure to leave the PhoneMode in DIAG, browse your kdz stock firmware file, and then click on "Lunch software update".
I'll be looking forward for your comment.
Please don't give up!

Same problem here. I downloaded a program called Optimus Toolkit, as I have an Optimus LGl45c, and the program is for
Linux. Same problem- CAN'T SEE PHONE. Program must use ADB, which CAN'T SEE PHONE while it's in emergency mode, as
apparently the correct partition isn't mounted!! Windows KDZ updater sees phone (try the solution from another blog- run in
different compatibility mode: right click on program>properties>compatibility. this worked for me) but the KDZ Updater can't
find the LGMobileDL.dll... lol! wait til you try it!...) So, for he/she who suggested LG PC Suite, please listen. Suite CAN'T SEE
PHONE either, and refuses to run any further....
Anybody have any tricky ways to flash a boot? It would have to be a Linux hack method.....
I think he did not check usb debugging so cant find phone
Not sure if it will work but no harm trying at this stage:
take out batteries,
wait for 30s,
put it back,
hold power and volume down
when keys light up, touch menu button (not the home button)
feel vibrate?
LOL!

K. A couple weeks later- for those of you with l45c:
You will get to the point where you find that LGNPST is the only thing that will flash. Having troubles registering the .dll? That cost me
over a week. Move the dll to your system/lg electronics/lgnpst folder and open the cmd window (terminal screen) as administrator.
Edit: Use the command> regsvr32 "name of dll".dll
You should google the regsvr command, as it is different for 64 bit machines, and there is a different system file to put the dll in..
Trouble is, we have no proper dll for the 45c. I tried the ms690 dll with an ms690 bin. Unfortunately, it flashed all the way through- and
now I have a perma-black screen... so don't try that.
I DO have an LGL45C-CT2 binary.... just no dll for the 45c, as usual. Not that it would matter- LGNPST cant see phone any more than
ADB could- there is no more 'emergency download'. I will check the battery, etc...
Morale of story- once again, there is evidence that the l45c is not supported. It is not an MS690, and probably not a P690... Use
LGNPST at your own risk, but quit pounding your head over other methods! Time wasted...
Until next time... keep hacking....

1.-uninstall the drivers and programs lg l7 on your pc.
restart your pc, and reinstall all programs and drives
for your pc to recognize the phone.
2.-remove the battery, press the power button and volume + and connect the phone to the pc, buttons go into emergency mode
Try this a few times.
you may need to perform step 2 more times
why are you trying to enter emergency mode ?

is your phone in bootloop ? or does it display blank screen ? (black or white)
did you try to remove sdcard ?
did you try to hard-reset ?
can you try to remove anything related to lg from your pc ? (all programs and drivers)
do you have qmemo button on top of volume buttons ? you can try to enter safe mode (most scripts will not work in this mode so you might get lucky)

Removing USB connection while flashing

Hi all,
I have a serious problem with my G2 which I could not solve: I used the new LG Flash Tool 2014 with stock KDZ file, everything was going just fine till I received an error message that LG server is not available, I disconnected the USB cable by mistake from my G2 and afterward I saw that it was in the middle of flashing process (12% was completed). I turned it off and tried to reach download mode again and nothing!, I'm receiving the "LG" logo and nothing- the screen goes black (it is still on).
I tried also to connect my phone to the computer- I received a list of 13 "new" local disks "H" to "T", only "H" disk is available and it's showing "image" folder with list of files.
I cannot reach "download mode", nothing is working!
I hope this is not the end for my G2..
please help me
Thank you so much!
If you could receive all those hard disks then you could maybe fix it with linux/ubuntu if you have it. Search for guides to cOpy the neccesary stuff bacK like the bootloader. I can't really help you atm as i am too sleepy.

Thank you for your reply. I found this on the sticky threads: "[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2".
I installed ubuntu and followed the instructions. when I type the following: "gdisk -l /dev/sde" I receive an error message:
"GPT fdisk (gdisk) version 0.5.1
NOTE: Write test failed with error number 13. It will be impossible to save
changes to this disk's partition table!
Problem opening /dev/sde for reading! Error is 13
You must run this program as root or use sudo!"
My device is not rooted, is this the problem?
Please help me!!
Thanks
@NNCa It says you need to run the program as root on ubuntu.
Just use sudo in front of the commands.
You need to type once your password to use sudo, you can't see the password if you enter it for safety I guess but just click enter after you typed ykur password.

Hi,
I powered off my phone by pressing volume down + power for a while ("LG" logo blinked once and phone was fully powered off).
I pushed volume down + power till I saw the LG logo, released it, and pushed again- and finally I reached the Factory Hard Reset screen. I have pushed 3 times the power, and I have got "Factory reset processing..." and nothing is appeared, even when I'm pushing several times on power again.
I guess this is the end of my G2 :crying:
Thank you all for your support, this is an excellent forum!:good::good:

Nope it isn't the end try to install the recovery again or try to push the custom twrp recovery again to the right partition! Dont give up that fast when i hear your things then its still fixable! you already got the factory reset processing so try to Push the Recovery again and search for an guide about recovery maybe Then you would probably get your device fixed.
Just read my things about simplicity so think easy and you can fix it. AND STAY POSITIVE You will repair your phone today :good:

Hi, sorry to say but you have unfortunately completely hardbricked your device. It happened to me too however I was able to get it replaced under warranty at no extra cost.
What happened was that when your phone was still detected by linux, you had a chance to recover by flashing the correct partitions to gain access to download mode and from there, flash a KDZ to go back to complete stock. However, the files you used were probably incompatible with your variant which has now corrupted your bootloader sequence. I suggest you read this reply by fizzy177 as well as the rest of the thread: http://forum.xda-developers.com/showpost.php?p=51522304&postcount=118
So right now, you cannot do anything as you have already found out, no computer will recognise that your phone is plugged in. Your phone fails to boot when you try enter the download mode and it just freezes on the splash screen which looks like this: http://www.lg-phones.org/wp-content/uploads/2014/03/image2.png
What's meant to happen is your phone should load past that initial splash screen into this http://www.androiddunya.com/wp-content/uploads/2014/01/LG-G2-DownloadMode.jpg which accepts KDZ flashing and warns the device has been rooted.
So it's a blessing that your phone cannot boot as LG cannot find out you have voided warranty and you will be able to get a replacement free of charge.
Issue was solved- device was fixed under warranty
Hi,
I just want to update you all that my device was fixed under warranty! (motherboard replacement)
Thank you all for help and great support, this is a great forum with great community :good::good:
Hello
From past 2 weeks i am wondering on internet for a solution . Hours and hours of surfing and articles but still
Hope some one solve this issue.
Okay. First i m using LG G2 F320 K update to lollipop . Non rooted. It was working fine . I can transfer files in MTP .
But about a month ago i get an update for my phone . And after some days i need to transfer some files to my phone , i wonder when i connected my phone to computer nothing happened . No notification on mobile for changing PTP MTP option . Also nothing happened in Computer device manager..
From that day i am unable to connect my phone with windows 10. It always charging mobile.
I uninstalled all drivers in device manager and installed from LG website. I updates windows N and NK MTP update from windows for windows 10.
I changed different data cables and different computers and different ports . All stuff i can do. Still no luck.
When ever i plug USB data cable it always put my Mobile on Charging . No notification on Mobile. Also i go in setting > storage> and there is no option in upper right corner to select USB PC connection .
I am in developer mode and debugging mode is on also. Also USB tethering option is Disabled .
Kindly some one help me regarding this.
LG G2 F320K updated to stock Koren lollipop 5.0.1 . Non root.( i updated lollipop in April 2015)
Issue i am facing is no notification for Charging/ MTP/PTP Usb Debugging on mobile notice bar when i attach my phone using USB cord with computer. Also in computer device manager nothing happen. Even i checked on windows 10 , 8.1, 8, 7 .
I remember it was working like charm 4 weeks before I can change MTP PTP or Charge only mode by selecting notification when i attach it to my laptop. I can transfer files can use LG PC suit .
Then i received an software update like 40 mb and i updated my mobile. That i remembered.
After that 2 weeks before i need to transfer some books from laptop to my mobile. When i plugged my device there no notification to select MTP mode . Also there is nothing happened in my windows 10. I looked in task manager. No yellow icon in computer task manager for driver thing.
Laptop is just silent and mobile is just on charging .
Then i go to setting in LG and looked for USB PC connection settings. I wonder there is nothing . Settings > storage > 3 dot in upper right corner.. it suppose to be there . But here is no 3 dot in storage. Then i looked into share and networks in android setting and i found that USB tethering. But its faded mean it is disabled and i am unable to use this feature also.
I tried on different computers different cables , original, but nothing. Always when i plug usb mobile went on charging and in all computers nothing happen in device manager.
USB debugging is on.. I factory reset device 2 times. but useless. Also i uninstall all drivers from my laptop and then reinstall drivers from LG website also i tried google drivers , ABD, different ports. Nothing nothing happen.
Also now if i try put mobile on download mode by turning device off and then push + vol button and then put cord in mobile . No download mode also it went on charging. Well charging from laptop or from charger is okay.
Hope i explain all.

help! my g2 only boots into fastboot

I was trying to install a custom recovery (twrp) by several different methods, with absolutely no luck (but that's another secondary issue at this point) and i screwed something up. Not exactly sure but i think the last thing I did was:
using "Rashr - Flash Tool" i think i went to "flash kernel from storage" then flashed boot.img.
now the phone goes immediately, directly into fastboot even without being connected to computer.
so i tried getting into the stock recovery by holding "volume down" and "power" until lg logo, releasing the reholding until factory reset screen. after choosing yes 2 times i get a
"boot certicification verify" or something message for about a second then it goes to this screen (sorry but apparently i haven't had enough posts on the forums to include clickable links.)

ok, i do have access to fastboot (actually, as soon as i power it on, it immediately is in foastboot mode, even without being connected to computer). i tried using srktool's repair tools via fastboot. it seems like it's working (ie phone shows that it receives command) but that's it. does it take a loooooong time or something?
btw, i can also get into download mode by holding "vol up" while plugging into computer. so, i tried using srktool utilites via download mode and nothing.
also, i just noticed that while connected to computer in download mode, in device manager it shows G2 under "portable devices" with an exclamation point on it.

I haven't taken the back off (yet) but all indications are that it's an AT&T (D800).
What part of my description makes you think that it might be a franken phone?
Did you try connecting the phone in download mode or fastboot to the LG Mobile Support Tool and performing an upgrade recovery?

not sure what you mean by "lg mobile support tool". i googled it and found and installed "lg pc suite". is that the same thing?
nevermind that last question. i found and installed and tried the upgrade recovery tool but for some reason the phone wont go into download mode anymore. when i power it up whith ""vol +" help down, it shows download mode for a second, but then goes right into fastboot mode.
Is it recognized by the program in fastboot mode?
Here's the program I was referring to: http://www.lg.com/ca_en/support-mobile/lg-LGD803
Even though the program says it is for the 803, I used it to recover my international d802.

Thanks for the reply! But when I have phone connected to USB in fastboot, it shows up in device manager as "android device > USB modem phone port". Is that method the right fix for my situation?
ok, so likei said my phone is indeed in fastboot mode, connected to computer via usb (shows up in device manager as "android device > USB modem phone port". using srktool, i can send commands to the phone (command shows up on phone but thats it.....doesnt matter what command, it just sticks there until i unplug the phone then srktool shows the operation competed and phone shows
https://drive.google.com/file/d/0BwQdFsCQ9KZVSVg3OTZLcXV0N0E/view?usp=sharing
but none of operations actually complete on the phone.

flash stock ROM via download mode or flash custom ROM via twrp.
the first choice (stock ROM) is better
thanks for the responses!!
before i saw your reply, i flashed the stock .tot firmware and now i have my phone back.
but, before all this started, it was lollipop(5.0.2) and now it's Jellybean(4.2.2). i bought phone on ebay, so im assuming that it got lollipop via an ota update. so now i'm looking into flashing it back to lollipop. what's the easiest method to install stock lollipop?

Mode download doesn't work

Hello,
I want upgrade my LG G2 with a new rom 5.xX
This phone have only the operator update. No custom, no trwp, nothing...
I installed drivers and when i want access to download mode. I can't. I use the good proccess with vol up then plug usb cable always with vol up presses.
follow this procces after a little moment my phone show me battery logo charging.
So i can't access to download mode.
I would use this process
t was NOT bricked. I finally tried playing around with the LG Mobile Support Tool (B2CAppSetup.exe). Of course it detected that my phone already had the latest firmware from T-Mobile, but then I clicked Options>Upgrade Recovery.
It downloaded for a while then I noticed it had put my phone into download mode (it said "Rooted" in red letters at the bottom). Then it flashed the same firmware over and I immediately tested, it entered download mode right away. But I didn't end up needing that as Stumproot was able to brute force it now after the recovery flash.
Anyway, I couldn't find an answer anywhere else. Most results also have a bricked phone, but that wasn't my issue. This solved my problem and maybe it could work for others.
but it's impossible for me to install B2appsetup on my pc the installation begin then stop after 5s then nothing.
I have Win 10.
Do you have a solution for me , please??
